I tested this several times to make sure I could reproduce the error last night. It was crashing the client but not the server every time. I tried it again after reading this and it didn't crash once. Not really sure what the deal is. I guess you can close this one. Must have been some kind of error on my server as I've not been able to reproduce it again. Sorry.

I have tried both auto and manual settings in the intel dialogue. It seems to me that set to auto my rain/wind settings seem to operate fine via script. It's only in the beginning of the mission that the setOvercast seems to completely fail, but I can't say with certainty that it works exactly as it should later on in the mission either. There is no doubt that it fails in the beginning though.

Now I'm starting to wonder if the setRain is working too. In the newest dev version I haven't been able to set overcast, fog or rain. I tested by setting up a couple of triggers with different weather conditions for each and running between them to see if anything changes and nothing. I really hope the weather issue gets some attention.

I have confirmed this problem as my dynamic weather system sets initial weather conditions via script but is not effective in regards to overcast settings. Does seem to work later in game session though.
